Supply functions in the ubiquitous Gorman class are examined for their homogeneity properties. Homogeneity places surprisingly strong restrictions on functional forms. These forms facilitate testing of aggregability given homogeneity or homogeneity given aggregability or testing both

Diminishing marginal utility is neither necessary nor sufficient for downward sloping demand, and it is not necessary for convex indifference curves. We illustrate these facts with two simple counter examples, using valid and easy to understand utility functions. The examples are accompanied...

This chapter presents the theory of consumer choice as applied to household behavior. An internally consistent, self-contained framework is developed for the analysis of consumer preferences, household production, quality attributes, and produced nonmarket commodities in static and dynamic...

Determining the impacts on consumers of governmental policies that affect the demand for food products requires a theoretically consistent micro-level demand model. We estimate a system of demands for weekly city-level dairy product purchases by nonlinear three-stage least squares to account for...

Numeraire prices that are measured with error create challenges for econometric estimation. A straightforward approach for a model with linear input demands, such as generated from a quadratic normalized profit function, is proposed where the numeraire price is measured with error. Numeraire...
